The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 - 4 µg/ml.
Recommend PFA Fixation and Triton X-100 treatment
1/50 - 1/200. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
FunctionActivates CDC42, a member of the Ras-like family of Rho-and Rac proteins, by exchanging bound GDP for free GTP. Activates JNK1 via CDC42 but not RAC1. Binds to phosphatidylinositol 4,5-bisphosphate, phosphatidylinositol 3,4,5-trisphosphate, phosphatidylinositol 5-monophosphate, phosphatidylinositol 4-monophosphate and phosphatidylinositol 3-monophosphate.
DomainThe FYVE-type zinc-finger is necessary for early endosome localization. Recruitement to endosomal membranes via this domain requires the presence of phosphatidylinositol 3-phosphate or other phosphatidylinositides. The PH domain is necessary for localization to the ruffle membrane. Recruitement to ruffle membrane occurs through binding of phosphoinositides by the PH domain. This domain also contributes to the lipid-binding properties of the protein. The DH domain is necessary for its ability to activate JNK1 via CDC42.
Cellular localizationCytoplasm > cytoskeleton. Cytoplasm. Nucleus. Early endosome. Early endosome membrane. Cell projection > ruffle membrane. Recruitement to the endosome and ruffle membrane requires the presence of phosphoinositides.
